I would discourage learning a language by writting a kernel (unless you
previously wrote a decent one). You'll run into issues that you won't be
able to easily debug, and very few people will be able to help you. You
might get away by doing that with much lower level language (C, ASM), but
that's pretty much it. Even C++ has some hard to debug corner case when you
Note: It doesn't mean D is not suitable for such a task. But I tried it
myself and run into more problems than I can remember. Some people came
with interesting solutions: I found

it blew everyone's mind at that time ;) ). Adam also had a talk at last
year's DConf, and an ebook you can easily find. Note that *the* place to go
for OSDev is osdev.org which has some (sometimes outdated) D-related topics
(and will give you exactly the same advice as me).
